My recent experience with GrubHub has been the final straw. What started as a simple attempt to edit an order became a total nightmare, and their customer service was completely unhelpful. ​I placed an order and noticed I needed to make a quick change, so I clicked "edit." Instead of updating my order, GrubHub's app placed a new, duplicate order—twice! I was now charged for three identical orders. When I called them, they said they couldn't issue a refund or credit because the orders were "already completed." This is absurd. A company can always issue a credit if they choose to. ​This isn't the first time I've had issues with GrubHub, but it's definitely the last. Their app is unreliable, and their customer service is unwilling to fix their own mistakes. I've deleted the app and I'll be taking my business elsewhere. Don't use GrubHub if you expect reliable service and a company that stands behind its product.
